I'm convinced that accuracy is 90% shooter, 10% gun. Yes, I know that some guns are inherently more accurate than others but, in fact, human error and talent probably remain the biggest variable in determining how accurately one shoots.
I've taught myself to be a competent shot with a double action revolver. By "competent" I mean 1 1/2" groups pretty consistently at 10 yards, and 2 1/2" groups at 15 yards. I can do that with any double action revolver I own and I can do it all day long. I am slightly less accurate at these distances with my 1911 but I attribute that to the fact that I've owned it for only a couple of months and have put less than 200 rounds through it. So, I'm still learning to shoot that gun.
Beyond 15 yards, it's a crapshoot for me. My 63-year old eyes just don't allow me to see what I'm shooting at well enough to be truly accurate at longer ranges. I could fire the most accurate handgun ever made and I still wouldn't get really good groups at, say, 25 yards. So, for me, the really fine points of accuracy are pretty much irrelevant at longer distances. I accept that I'm a good shot, sometimes an excellent shot at shorter ranges and that I truly suck at longer distances. Short of putting a scope on my guns, I'm left with that reality.
My guess is that most of you are like me. Your vision may be better than mine but other factors almost certainly interfere with you wringing the absolute highest possible degree of accuracy out of your guns. So, I suspect, for most of us, this discussion of what is "super accurate" is interesting but, in reality, pretty much irrelevant.
